She really seems like the type who would freak out if she knew what you were planning to do with her. You would like her to enjoy this, but you also really want to get your rocks off with this kid.
"Alright, we are gong to move onto your punishment now Suzy." You tell her and then stand up and go to your desk. You pull out a blindfold, meant to be used to conceal the identity of the punisher from the child, particularly in cases of homosexual activity during the punishment. In this case though, you will use it to keep her from knowing what you are touching her pussy with. "Ok Suzy, you are going to wear this blindfold, and then I am going to touch your privates some more. This is your punishment. You are going to get some strange feelings, but it's all Ok."
Suzy nods and sits up, presenting her head to you so you can lower the blindfold around her eyes. She seems to have gotten extremely docile and quiet as soon as you opened her diaper. Having the blindfold on actually seemed to relax her though. She lays back down and spreads her legs a little further as you continue to massage her pubic region. Now that you have given yourself free license to man-handle her genitals in any which way you please, you begin to focus more on her slit. "Oh, one more thing Suzy. No talking during this punishment. You cannot say anything, and I will also not say anything until your punishment is finished. Ok? Do you understand Suzy?"
"Mmmm..." She grunts and then nods her head meekly a few times. Satisfied with this, you gently begin to tease her clit, still hidden under its hood. You know better than to go straight for it and expose her directly, that would just be too much stimulation for a kid her age who has almost certainly never been touched like this before.
Suzy is very stiff, and she starts gripping the sides of the changing table. She lets out a small whimper. You tease her clit a little more, and then begin working your thumb inside her untouched vagina. She jumps slightly at this and her entire body goes twice as stiff as it was before. "Mmm.. Mr... Ahhh.." She looks away. "Sorry."
"It's alright, but don't let it happen again." You tell her. The whole point of not having any words spoken between you was to keep her from getting any information as you moved forward from here. You would get her used to your thumb in her pussy, then she might not be as attentive when you switched it for something else.
This is going to be a bit of an issue though. You wanted her to possibly enjoy this a bit, maybe give her an orgasm, but with how stiff she's being you do not think there is very much chance of that.
